This is a slightly non-standard configuration so it breaks things. It doesn't happen on Debian. Anyway the fix is very trivial, just configure guestfs-tools and virt-v2v like this: ./configure CFLAGS="-O2 -g -fPIC" Actually I have a ./localconfigure script which wraps my very long and complex ./configure line (note that .gitignore ignores any file matching local* for exactly this reason).
